I have to tell you that most experts discount almost completely satanic ritual abuse. I was a youngish adult during the 80'-90's when it was quite a thing and saw psychiatry using it as a legitimate diagnoses and police actually thinking it was real. It has almost always been discounted. I do believe some people are crazy enough engage in this behavior but it was mostly a phase that the country went through and psychiatry went through.
btw, you have three threads about this.
